Root Explanation
Overturn is formed from "over-" (meaning above or excessively) and "turn" (from Old English "turnian", meaning to rotate or change direction). The word means to turn something over or to change its position completely, often in a dramatic or excessive manner.
Memory Tip
Think of something being turned 'above' or 'excessively' — 'over-' suggests going beyond, and 'turn' means to rotate. This helps you remember that to overturn means to turn something completely over.
